HEATER FOR INTAKE-MANIFOLDS.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed February 12, 1918. Serial No. 216,819.

To all whom it may concern:

Be it known that I, Gnonen WV. BARBER, a citizen of the United States and resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Heater for Intake- Manifolds, of which the following is a specification.

The object of my invention is to provide a heater of simple, durable and inexpensive construction for intake manifolds of engines on motor cars and the like. 7

Still a further object is to provide such a heater, which can be readily and easily mounted on the intake manifold or removed therefrom without the use of tools or of bolts, screws or the like.

Still a further object is to provide a heater, which occupies very little space when installed on the manifold and when not in use will. not be in the way. With these and other objects in view, my invention consists in the construction arrangement and combination ofthe various Parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation of an engine equipped with a manifold heater em bodying my invention.

Fig. 2 shows a rear elevation of a heater.

Fig. 3 shows a side elevation of the same partly in section. 1

Fig. a shows a horizontal, sectional view taken on the line 4-1 of Fig. 1.

Fig. 5 shows a vertical, sectional view taken on the line 55 of Fig. 3.

Fig. 6 shows a side elevation of a slightly modified form of my invention; and

Fig. 7 shows a front view of the device shown in Fig. 6.

In the accompanying drawings I have used the reference numeral 10 to indicate generally an internal combustion engine having an intake manifold 11 with the lower cylindrical portion formed with an elbow 12, which is connected with the carbureter 13.

My improved heater is designed to be mounted on the elbow 12 of the intake manifold adjacent to the carbureter. My heater comprises an outer layer A of metal, a middle layer B of asbestos or other non-heat conducting material and an inner layer C of metal.

The heater consists of a substantially vertical rear wall 14 and side walls 15. Near at 19 is cut away and the side walls 15 at the upper end ofthe heater are formed at their forward portions with curved adjacent members 20. The metal of the walls 15 is resilient and the members 20 form a spring clip device whereby the heater may be locked on the manifold by frictional engagement. At the forward upper portion of the extension 16 the side wallsof said ex tension are provided with similar curved spring members 21 adapted to normally stand close together but capable of being sprung apart for permitting the heater to be mounted on the manifold.

At the lower part of the heater is a metal box or receptacle or pan 22 and above the receptacle 22 the side walls 15 are provided with. ventilation openings 23. It will be seen that on account of the angular shape of the rear portion of the heater, flues 24 are formed. In the rear wall of the heater is an opening 25 normally closed by a spring controlled door 26 in which are ventilation openings 27. It will, of course, be understood that the heater may have a three layer bottom 28.

In the practical use of my improved manifold heater, the device is slipped on to the manifold by springing the members 21 and 20 apart until they pass the cylindrical portions of the manifold on opposite sides of the elbow for inclosing the elbow in the heater. The door 26 is then opened and a suitable fuel, such for instance, as a cube of solid alcohol or the like is placed in the opening 22 and lighted. The metal is thoroughly heated for supplying warm mixture to the engine for starting in cold weather.

In Figs. 6 and 7 I have shown a modified form of my invention. The construction in upwardly extendingarms 31 clearly shown in Fig. 6 and adapted to be benttoward each other around the horizontal portion of the intake manifold pipe. It will be understood thatthearms 30 and 31 are made of sheet metal of any suitable kind to permit them to.

be readily bent around the manifold.

In the form of the invention shown in Fig. 6, the device is readily and easily slipped on to the manifoldpipe at theelbow,

with the upright portion of the intake ma-n1 fold received between the side walls 15, and with the extensions 30 projecting slightly beyond the upright portion of the intake manifold. The horizontal portion of the inanifold is received between the walls of the ex tension 16 with the arms 31 projecting, upwardly above said horizontal portion. The arms 30 are bent toward each other for receiving and holding the upright part of the manifold, and the arms 31 are bent toward.-

eachlother, for receiving and holding the horizontal part of the manifold, whereupon the device is installed on the manifold. This installation can be accomplished without the use of any special tools, or bolts or screws or separate parts- The operation is the same with the modified forin ofvthe invention.

The solid alcohol is inserted through the opening at'the back of the device into the interior and may be lighted and burned as desired.

It should be understood that the pan or receptacle 22 may be used or not as may be desired. I

Copies of this patent may be obtained for In both forms of the device there is provided at the forward end of the device at its lower portion a short upwardly extending wall 32 the upper edge of which is curved to fit the manifold as at 33.

The advantages of a device of this kind are seen from the foregoing statements of the obj ects' and description of the invention. The deviceis extremely simple and an inexpensive construction and may be quickly and easily installed on the. manifold or taken therefrom. It requires no tools and no bolts, screws or detachable parts. It requires'no complicated or expensive'fuel supply system.

some'changes may be made in the construction and arrangement of the various parts of my improved manifold heater without departing from the essential features and purposes thereof, and it is my intention to cover by my'claims any modified forms of structure or use of mechanical equivalents, which may be reasonably included within the scope of said claims.

I claim as my invention:

1. A manifold heater comprising a receptacle, having lateral and upward extensions provided respectively with members designed to receive the upright and horizontal parts of an intake manifold elbow and to engage them, said receptaclehaving an opening in its wall and having means for spacing the bottom of said receptacle from'the lower part of the manifold. V

2. A manifold heater comprising a receptacle, havingflateral and upward extensions provided respectively with members designed to receive the upright and-horizontal parts of an intake manifold elbow andto be moved to position to engage and hold them, said receptacle having an opening in its wall and having means for spacing the bottom ofv said receptacle from the lower part" of the manifold.
